charge. measuring device theret r, my ob ject being the provision of an arrangement for measuring the discharge, as "for instainse, in the case otdose regulation from medicine bottles.

My invention moreover,proposes a device which from its nature is capable of formation in various ways, either integral with or separate from a bottle, jar and (he like, and from various materials.

In the accompanying drawings illustrating my present invention,

Figure l is a side view illustrating a bottle tilted in its'initial position for discharge and equipped with my invention.

Fig. 2 is a view showing the bottle righ ted in the second position with a measured dose in its discharge neck,

Fig. 3 is a View showing the bottle inthe third or dose discharge position,

Fig. 4 is a vertical section through neck of a bottle with my improvement-i plied therein, and

Fig. is a detail perspective view of the liquid separating plug.

Referring now to these figures, and par-- ticularly to Figs. 4 and 5, and bearing in mind that-I have for the purpose of ili'ustration selected that form in which the plus,

the

' is made separate from the neck of the bottle,

even though the invention is susceptible of integral formation, I have shown a bottle at 10 with a normally stoppered discharge neck 11, the stopper of which appears zit-12.

My invention in the form of a plug 13, constructed of any suitable material, arranged to interfit the neck 11 and is introduced therein and preferably located adjac'ent to the base of the neck or at such point along the neck as will leave the desired space for a dose of the liquid contents of the bottle between the upper end surface of the plug and the stopper 12.

As shown, the plug is for the above reasons cylindrical and this plug is provided with diametrically opposed grooves 14 and 15, which when the plug. is

introduced inthe bottle neck, form channels I betweenthe plug and the inner surface. of

the bottle neck.

Fignin particular makes it plain that the groove 15 and thechannelltormed there.- by are of considerably greater length than the groove 14 and the channel formed there'- y, by virtue of the fact that one end oiithe plug 13 is cut away at a considerable angle with respect to the opposite. end hoth of the grooves and the channels formed there,- by, communlcating at their opposite cnds with the dose. receiving-space above. the. plug.

and the interior of the bottle 10 below the plug.

By virtue of this construction and with the stopper 12 in place, the bottle may be inclined with its neck downward and with its longer channel 15 lowermost in the position shown in Fig. l, where the pressure of the fluid in the lower channel will force air from the space between the plug and the stopper and into the bottle through the shorter channel, so that when the bottle is righted in position shown in Fig. 2, the air having been displaced from above the plug 13, the liquid in the dose measuring space will be held therein, and prevented from running back into the bottle.

ll'loreover, when the bottle is tilted in an opposite direction, or in other words, with the short channel down and the long channel up and upon removal of the stopper 1.9, the liquid within the dose receiving space between the plug and the stopper will be allowed free escape and the remaining fluid in the bottle at the same time held against discharge.

\Vhere the plug is termed separate from the bottle, as I have described and shown, it is obvious, that the dose receiving space may thus be readily adjusted by shifting the plug lengthwise oi? the bottle neck, but it is to be understood that my invention in its broadest aspect contemplates that the plug which thus forms a li uid separating device and means by whic measured quantites of fluid may be intermittently discharged,

lengthwise wvhich grooves is substantially longer than the other by virtue of i the said angular end of the plug, as described.

2. A liquid separating device for a liquid container having a stoppered discharge neck, consisting of a plug adjustably disposed within the said neck, having its outer end cut away on an angle with respect to its inner end and having diametrically opposed lengthwise grooves cominunicating be- 7 tween thesp-aces upon opposite sidesof the *plug and one of which is of substantially greater length than the other by virtue of the said angular end.

3. A liquid receptacle having a stoppered neck and means separating its body from its said discharge neck, having channels conimnnicating between the body and its neck at spaced points, one of which channels is oi greater length than the other.

t. A liquid receptacle having a stoppered neck and means separating its body from its said discharge neck, having channels coinnninicating between the bottle and its neck at spaced points, one of which channels is of greater length than the other, said means being in the form oi a plug adjustable with in the said discharge neck, for the purpose described, V

5. A liquid receptacle havin a stopnored discharge neck, and means located in the neck whereby to form a liquid receiving space adjacent to the stopper of the neck and apart from the body of the receptacle, said means having channels therethrough at spaced points communicating between the said liquid receiving spaces and the body of the receptacle and one of which channels is substantially greater in length than the other.
